COMPRESSION-VALVE FITTING.

Specification of Letters Patent.

Patented Apr. 5, 1910.

To all whom it may concern:

Be it known that I PHiLIP Mummnn, a citizen of the United tates, and a resident of Decatur, in the county of Macon and State of lllmois, have invented a certain new and useful Improvement in Compression- Valve Fittings; and my preferred manner of carr ing out the invention is set forth in the f0 owing full, clear, and exact description, terminating with claims particularly specifying the novelty of the same.

This invention relates to baths and closets,

to bath and basin fittings; and the object of the same is to produce a fitting having a lesser number of joints than heretofore and wherein the compression valve stands at the juncture between the air chamber, the cock supply, and the main supply, and therefore avoids the necessity for an elbow and additional joints in the sup ly.

To t end the invention consists in a construction of which one embodiment is described in the following specification and shown in the drawings forming a part thereof which illustrate its a plication to a bath tub although it will be c ear that the invention may be used with a basin or other lavato member.

said drawings, Figure is a central vertical section through the valve body.

Fig. 2 is an elevation of the entire fitting with the valve body in section. Fig. 3 is an end view of a bath tub showing a compound cock in dotted lines and illustrating the application of two of these fittings thereto as for hot and cold water. is

Heretofore, when it was desired to construct a fitting of this character having an air chamber, it was customary to mount the latter on a combination tee and elbow fitting connected with a supply pipe and apart from the valve, the latter being let into the supply at a lower point and with joints above and below it. Broadly speaking, the present invention avoids the necessity of such a combination tee and elbow fitting by making it a part of the valve body, and avoids the necessity for said joints by utilizing for the same purpose the joints which connect the body with the various parts.

Referring to the drawings, the numeral 1 designates as a whole the valve body herein shown, as a single casting having four arms, of which that numbered 3, at the top, com- .upright partition 6 municates preferably that numbered 5 in alinement with it, at the bottom, is the water inlet, that numbered 4 at one slde is a water outlet here shown proecting at right an les with the body and formed into a 90 e1 w, and that numbered 2 at the opposite side is a housing for the valve stem.

A part or all of the arms just referred to may in their connections difier somewhat from what is above pointed out, as for instance, the arm 4 may carry the air chamber and the water outlet pipe be attached to the arm 3. The same is true of the further deta l description given herein, bearing in mind that the arms may serve different purposes by an interchange of connections in various parts and detail, but still bear the same general relation as herein referred to.

The valve in the present instance is of the compression type, the valve-disk 7 closing horlzontally against a seat 6 formed in an across the body, at one side of which is the valve chamber 6. It will be seen that this valve seat web 6 divides the valve casing dia onally, so as to bring on the inlet side 0? the casing two branches, namely, the main mrvice supply branch 5 and the valve housing branch 2, and on the outlet side of the casing, the air chamber branch 3 and the cocksupply branch 4. The disk is held in any suitable manner, as by a screw 7, to the valve 7 at the inner end of the stem 7 which passes through the cap 8 and carries a handle 7. The cap engages exterior threads 2 on the housing, and the latter is interiorly threaded as at 2 to engage threads on the valve stem as will be well understood.

The air chamber connection 3 'is provided with internal threads 3 to receive an upstanding air chamber 3 which has a cap 3; further details of the construction of this chamber are unimportant.

The water inlet 5 is internally threaded as at 5 to receive the main suppl pipe 5" which is here shown as leading ownward through a floor flange 5 to the service pipe not shown, although this supply pipe might be bent and connected with an exposed ice pipe or pass into the wall.

The water outlet as at 4: to receive the cock supply i t" which leads upward parallel but out o 2: incment with the main supply, to the cock (not with an air chamber,

t is internally threaded 7 shown) and which may ormay not have a coupling or joint 4 here illustrated the cock supply hasa bent connecting end 9 and a union coupling nut 9 is provided for connectin this end with the cock as well understoo The various arms of the valve body are preferably beaded at their outer extremities, and all parts may be nickeled orotherwise ornamented for the sakle of neatness, or to prevent rust or tar- IllS It will be observed that branches 3 and 4 have their terminals parallel and on a level with each other, and furthermore, that the said terminals are threaded at 3 and 4 respectively, with standardthreads and of the same bore or internal dimensions so that they are standardized and adapted to be inter-- changed, whereby the air chamber 3 and the cock-supply connection 4: may be as readily connected with the one as with the other; thus giving a range of adaptability to the fitting which would not otherwise be the case.

In setting up this improved coupling, the

air chamber is first attached to the valve b body,the latter is then connected by the supply pipe with the service, and finally the coc supply is attached at one end to the valve body (perhaps adjusted in its length as at 4 if necessary) and then connected with the 000 If the fitting be attached to a tub as shown in Fig. 3, two will usually be required, preferabl a right and a left, as illustrated; and if 1t beattached to a basin, the cock suppl pipe may not have the bent connecting en 9 but might extend straight upward toward or through the basin slab as well understood.

It is not necessary that the valves be right and left, owing to the interchangeability of the valve for its adoption to the place in which it is used, bearing in mind that the same can be turned and set up in any position relative to the inlet and outlet connec-' tion, so long as it is within a circle of which the radius is from the center of the valve body to the outside of its longest arm. This adaptability in doing away with the necessity of right and left valves reduces cost'of manufacture and assists in efficiently setting up and applyin the device, and avoids the carrying 111 stoc of two kinds of valves by the plumber.

After the fitting has been set up on opening the valve as shown in Fig. 2, the water will be admitted from the supply pipe and will pass through the valve seat, to and through the outlet 4, and upward through the cock supply to the cook, the air chamber forming a cus ion as well understood in fittings of this character. On closing the valve, the pressure is shut off simultaneously both from the cock and the air chamber. It will be observed that this fitting necessitates only within its length. As
